Energy Efficient Multipath Routing Protocol with Guaranteed Data Delivery for Wireless Sensor Network

The current challenge in wireless sensor networks is high data delivery ratio with low energy consumption. In this paper, a node that has collected maximum amount of data (buffer is maximum) is given first priority to access the channel, and send the collected data to the Sink through greedy routing. To achieve high delivery ratio with low energy consumption, data is forwarded along a multiple path to save energy, and a high data delivery ratio is achieved by path repair whenever a break is detected .We propose a simple path repairing protocol , whereby a node can skip over path break. Some of the important parameter like packet delivery ratio, path set up time and data transmission time; are studied.
